Derived Data Types
Arrays and structures are handled as derived data types.
Accessing One Member
The data format for accessing one element of an array or one member of a structure is the same as
the data format for the corresponding elementary data type.
Example: If you specify V
ar[5] to access a variable defined with UINT Var[10], use the same data for-
mat as for UINT data.
Accessing More Than One Element at the Same Time
Arrays
• Accessing an Entire Array
If you access an array variable without specifying an element, the entire array is accessed.
